I'm trying to extract the BIOS and MICOM images from the samsung official updater in order to perform the upgrade with the method described here.

I don't know why, the extracted BIOS image size is wrong.It should be 2MB, but it's like the last bytes are truncated, resulting in an invalid image. And that's odd, because it seems the official updater performs the upgrade just fine.

So, at the moment I'm unable to test it.

Please consider a little donation to keep the 'Linux On My Samsung' project up and running. Thank you!

I have the two extracted BIOS files and used Voria's method above to try to flash using a DOS usb thumb drive. It get's stuck at saving the original BIOS and never gets past that part. I have the 11CA BIOS files though.
